Fight off asthma and ER trips with nutrition

Some experts believe that you may reduce your asthma symptoms by eating certain foods. Many fruits and vegetables contain potassium and magnesium. Avocados, bananas, and potatoes are especially rich in these nutrients. Legumes, nuts, dairy products, and whole grains also have potassium and magnesium. Not eating enough foods with these nutrients has been linked with poor lung function.

Fruits and vegetables also contain vitamin C and a nutrient called quercetin. Some experts believe that vitamin C may help treat allergy-related conditions like asthma. Quercetin, which slows the release of the chemical histamine, may also be helpful. Histamine in the body causes allergy symptoms.

Consider eating foods high in omega-3 fatty acids, too. These foods include fresh fish (salmon, mackerel, and halibut) and plant oils (flaxseed oil and walnuts). Omega-3 fatty acids may help reduce swelling and improve lung function in adults with asthma.

It's not known for sure yet whether these dietary changes can improve your asthma, but it won't hurt to try them. Just be sure to continue taking your asthma medicine as directed.
